Thanks David and Lee The Alltrax document depot has an AXE Diagram (Doc100-046-A_DWG-AXE-Reverse-No-PlugBrk-wire-dia.pdf) which shows this diode as MR752 or 6a06. Basically a 6amp diode. This goes on the key switch/ power pin. You also need a resister and diode down on the contactor to prevent reverse feedback and to keep the caps in the controller from surges. I have a new SPM controller on order and it doesn't require either diode provided the contactor is connected to the controller's provided contactor pins. Hoping this controller will give me better service and the Cougar I am building will be much more serviceable. What really irks me was that their support told me moisture wasn't the cause when obviously it was, I would have spent a lot less time troubleshooting. Once you epoxy something it's nearly impossible to service, when what was meant to protect fails it also blocks it's repair!
